I’m one of those people that recoups my waste copper and refines it to pure copper to be used again. I’m actually getting ready to filter 3 waste buckets full of cemented copper and melt it all down. Then it goes into my copper cell to become pure again. Extremely cheap to do really. I wish I wasn’t a couple states away from Sreetips because I would gladly take that waste copper off his hand instead of him trashing it.
@@djcbanks I actually considered setting up a copper cell as something of a "practice" for gold and silver since a screw up wouldn't mean real money lost.
I started watching these a few months ago and I think I would enjoy refining. Just the mixing and desolving and melting just seems like i would really enjoy it
People don't know the struggle. lol A lot of times all they see is how easy we make it seem. That's only a couple of steps to get from A to B. Then we have to go from B to Z to process the waste. It's a labor of love!
@@sreetips Very few times do i do incineration. Most of the time it's to aid in filtering from dirty GF or Karat. When i do a stock pot, once a year, i drain it then wash the residues two or three times with clean water and let it settle in the bucket or drum each time. Then i just pour the residues into a beaker, let it settle, draw off the excess wash, and roll with it. I haven't found incineration very useful in stock pot processing. Mistakes are how we learn brother. I use a pyroceram dish for incineration. Those things can glow red hot and not break or melt when you heat them slowly and cool them slowly. I've even melted zinc and lead in them before.
I know I said this on the first stock pot video, but it really is such a huge undertaking. We usually see the glamorous part of refining with the pretty reactions and what not, but the reality is that there is waste produced and it has to be dealt with. Not just to get the remaining precious metals, but also to responsibly dispose of what’s left after those pretty reactions.
Another great learning experience. If I may I learned a nice little trick the last time I cleaned my stock pot out. After I filtered a bunch of the solution out I used it to rinse out the dregs from the bottom of the bucket. That way no worry about what water might do and no need for more acid. It flushed everything out quite nicely and i only needed about 50ml of HCl to fully rinse the bucket clean.
Very interesting series, screetips, I can't wait to see the rest of the processes. That sludge pot had some ugly goop in it, and I was thoroughly impressed with how you drew out the precious metals from it. I'm off to watch part 2, and I'll see what happens next!
Thank you so much sreetips! I don't know why, but these stock pot videos and others where you recover precious metals from wastes are my favorite videos on your channel. I think it's the idea of getting something valuable from what others might throw away!
You made the right choice on not pursuing that black mass, I believe that is crystallized salt, carbon, and a tiny bit of silver/copper that got stuck in the crystalline structure.
Your mistakes and troubleshooting are probably the best parts of your videos. We may never have one of them happen, but when we do, seeing it happen to you and how you resolved it is a blessing!
Great to see more of what happens after the gold/silver refining and how you get the metals back from what doesn't precipitate. On a side note, instead of throwing away the copper since you can't use it, you could melt it in a crucible in your furnace, pour into an ingot and sell to a scrapper. It may not be a precious metal but it does have some value.
@@sreetips I don't know the online price in the US for kilo bars of copper, but I assume you would get somewhere around $20-25 for a 1kg bar. pretty expensive if you ask me.
@@BratislavMetulskie copper is currently $4.36/lb and one full size ingot I pour usually is about 6 pounds which makes one bar $26.16. A 20 pound propane tank here in Maryland cost less than $20 to swap a tank, less than $15 to fill it. You can melt easily 10+ ingots with one 20 pound tank of propane. It easily pays for itself, just no where near what precious metals make per hour of your time which is the angle Sreetips comes from. It’s not worth his time but there is plenty of money to be made from waste copper. Edit: I want to add you still need to refine the copper to get that price because it won’t be pure and that’s where the time to recover increases dramatically.
you may use a cupelle (for refiner), sort of tick dish, with lead or bismuth, and leave for hours in your electric oven, the not-noble metal will oxydise and disappear, and copper too if temp is above 1100°C. at the end you will find a button in gold, silver & PGM only.
The issue here is the intent was to separate out each metal in the sludge for refinement and then for sale. Not to just collect out a mixed bead of PM that now needs to get all acid waste city done to it breaking it down again just to separate the metals. The metals were already broken down to a very fine state in the sludge, easy to work on.
Mr STEETIPS, it is amazing how your projects are always relevant to what I am currently putting in practice. Up to now, I used to have several gallon-sized temp containers used as “semi-stockpots”. After a lot of practice, mess, mistakes and other, this weekend was the very first stock pot solids processing I formally ran. Now I wake up first thing I come up to is your StockPot v3 up and running. I never have excess nitric when processing scrap or placer. However left over solids have been a challenge. It seems they never finish reacting. Lets say I started up with whatever volume of HCL and 30mL of HNO3. It stops reacting, then I started incrementing adding nitric. It is like forever, . Also, imagine I incrementally added other 30mL. When reacting stops I recover the gold. If I go back and re-process the filtered solution, it starts all over and I drop more gold (less but still). It is driving me insane (it ja not an isolated case, whatever filtered out solids I either re-process or accumulate before re-processing will eventually yields me more grama of gols). Have I fouls the gole egg laying goose?
SREETIPS "Now I'm completely BAFFLED"!!! ME- MAN,you dont usually hear those words together here on this site. Mrs. SREETIPS-"Honey,you've been at it to long,,,,come get some soup!"
bulk copper may not be worth it but that copper solution could be turned to copper nanoparticles with some detergent and citric acid and sold for MUCH MORE. Copper nanoparticles are worth more than the silver you are refining, and since it is already mixed with solvent costs you only as much as the citric acid does.
@@sreetips I do, if you tell me where to send them, I will send you some samples. I am in Germany though, so shipping is expensive. You can make them yourself pretty easily, and with the right mix of ingredients, ph, and heat you can control the shape from hexagonal to cubic and the size. The control of size and shape is what makes them valuable, and you will need to perfect your recipes before you can market them.
No one is talking about recovering the copper. Melt the cemented copper that has other metals mixed in, into small ingots, 1 or 2 pounds and stamp them with sreetips or whatever you want than sell them for $20 to $25 each SINCE so many people would love to have something you made but cant because of the crazy prices everything else sells for. Turns cheap copper into a money maker for you.
I hate to say it but I like it when it goes wrong. To me it just proves that Mr sreetips is human and learning too. I'm glued to this channel now. Keep up the good work.
It's not about the copper when people talk about recovering it. Recovering the chemicals is way more beneficial. For the copper it doesn't matter and it is just a byproduct. You get almost the same price for your cement copper at the scrap yard as you'd get for electrolytic refined copper. And I like waste free material cycles. But my operation is on a much smaller scale.
I watch a lot of metal melting channels and I have seen a couple videos where they made a mixture of copper and aluminum. Once you start to get over 11% aluminum, it starts to get more brittle. Different metals in your case, but the same principle. The mix might have some other stuff in it as well that didn’t mix well. Good video. I enjoyed it.
Since the silver came from karat gold refining, known carrier of platinum group metals, it will have other precious metals in it such as gold, platinum, palladium. Even rhodium and iridium. These metals will cement out with the silver on to the copper we place in the silver nitrate liquid. They will then be present in the silver granules that we made by pouring the molten cement silver into the water. The PGMs and gold will not dissolve in the silver cell anode basket. They get trapped in the anode filter as slimes. But the copper and silver, being soluble in the electrolyte in the presence of electric current, will dissolve and pass through the filter. Only the silver plates out on the cathode. The copper stays in solution and builds up in the electrolyte turning it blue. If we keep the right conditions of current flow, pH of electrolyte, and silver and copper concentration all in specific limits, then the silver, being the only metal to plate out, will be very high purity. Close to five nines. That’s 99.999% pure silver. And it’s just beautiful.
The Sludge from the bucket is already in a super fine state, why incinerate it at all, just go right in to solution and start separation of the metals. Pour it out of the filter and rinse the filter and add it to the filter pile of just ones from the stock pot for later refining. You basically did a flux reduction with only using borax as the flux. The cap is the borax with some base metals pulled out in a slag matrix, then harden off as cooling. Using a unseasoned melting dish is also got me saying "Things that make you go HUMM?"
Hey Sreetips! Thanks for the video!. I noticed that you were running an acetylene rich flame (carburizing) which could add carbon to the melt . I sent you a link in your email. keep up the good work!
The copper in the bucket is that pure copper powder that can be melted into bars ....if so there is plenty of people that love making jewelry or small stuff out of copper and aluminum .....
Love it buddy but meanwhile i have a bucket with scrap copper not worth much... Wish i could just throw away copper but its hard these days.... Thank u as always for the precious knowledge
I beg your pardon to make a small addend: there's no reason for a precious metal refiner *in the US* to recover the copper. It is quite valuable in other countries, as a matter of fact.
Nice video sreetips. I would assume that brittle crust was silver chloride mixed with borax. You used HCl to clean out the bucket, thus creating Aqua Regia with those filtered solids. Then later you added the silver sterling to your melt as collector. Chlorides were still in that molten mass. So it formed silver chloride while being molten. It can not alloy with the rest, which should be a mix of Pd, Au and maybe some other exotic PMG stuff. Cheers, Marcel
@@sreetips This is the first comment I've seen mentioning this. I've worked with borax flux a bit and it makes glass (like what you had there) when melted. So I think Maboo above is right, and what you made is silver infused borax flux/glass. Cheers!
I was only thinking recently this must be due soon! Cant wait to see this Sreetips will watch when I have the time. New knowledge and skills will make this even better I am assuming. Cant wait
Looks like you've got some interesting folks watchin your videos Sreetips . I always read some of the comments and look forward to see what you discover in that "puck" .
Hi Thanks for the videos you share on UA-cam I dissolved five kilograms of computer boards, including RAM and CPU, first with nitric acid, and after filtering and washing the boards, they were dissolved in acidic acid, then neutralized with urea, and finally with smb powder. The color of the solution changed to brown. Yes, but after 12 hours, no sediment was obtained. Thank you for your help
Very interesting on how the brittle has no precious metals except silver. Can't wait to see how this experiment shows what happened and why it separated from the other metals. My brain has been tickled haha
Sreetips: Copper is by far one of the most toxic metals when it is in solution and were it copper chloride I would agree with you that putting it through cementation in your iron tank would be very effective. However, Copper Nitrate does not react as well with iron and produces a mix of both Iron nitrate and copper nitrate in solution afterwards. Have you considered the Copper Cycle? Copper Nitrate is mixed with a small amount of Sodium Hydroxide (Lye), allowed to convert into copper Hydroxide and sodium nitrate. If you then heat the solution ( I put it outside in sunlight on my back porch) it converts the copper hydroxide to copper Oxide which is easily filtered and can be bagged and sold or contained, labelled and disposed of safely. The clear solution leftover makes a very good fertilizer and is copper free. Give it a try!
Yey! another Stock Pot! Let us see how much you can recover this time. and for the copper-stuff: How about sending some of it over to BigStackD? He can make some nice stuff (maybe even "Nordic Gold") from it and melt it into an ingot.
Your high temperature oven is an exceptional tool. If you have a cupel, you could have added 10 grams of lead to the melted metals that got you side tracked, and it would have oxidized off the crap metals, and the result would have been a Precious Metal button, that you could then add your silver to if you wanted to inquart and the refine as you normally would. The benefit of cupelling is that 99.99% of the trash metals are oxidized off into the cupelling cup and all you have left is pure precious metals. Since you have the perfect tool for the fire assay process, seems a shame not to use it for just this situation.
@@sreetips Jason @ mbmmllc has lots of videos about doing the cupellation process. I know you're a busy man, however, one more tool in your tool bag wouldn't hurt. You're channel is the most instructive in so many ways, so Thank You for your incredible work and instruction.
Cuppelation is not beneficial here. There is very little base metals. Only metals copper and above. It was an incineration step, it wasnt meant to be melted into a bead. The acids are what sreetips knows and does very well. Thoudands of hours of research, trial and error. I suspect sreetips will eventually forgo incineration entirely in his stockpot videos as his process develops.
@@NOFX0890 "fire assay" is the primary step in commercial precious metal processing. If being contrary just to be contrary was you goal, congrats. Learning additional processes, is never a bad thing.... so exactly what was your point?
You would likely benefit from the information on alloys available through the use of a hand held or bench model XRF analyser set up for precious metals. It must be great to a print out of the alloy of a lump of random waste alloy, it would also give you a map to the recovery route for each precious component of your metal wastes.
$23k to buy. $1500 per week, $4500 per month to rent. Plus a visit from local authorities to verify proper use (because it shoots radiation). I’m nearly flat broke and deeply in debt - too rich for me. I’m just a poor-man’s hobby refiner.
you know that your local scrap yard will buy that copper right? seems sort of wasteful to throw it away when you could get something for it even if it is just beer money...or is that what you meant when you said you were going to toss it out?
Even if you can't get much or anything for it from the scrap yard, it's still a waste to just toss it. The impact of mining and refining is pretty significant; most metals are basically 100% recyclable, compared to plastic, which basically doesn't get recycled at all. And that bucket of copper still has a lot more value than chasing like a few grams of silver during refining. If copper is valuable enough that people steal it from construction sites, it's valuable enough to recycle.
Too bad you aren't local. I would like to try my hand at refining some of the metals out of that copper through electroplating. Its not worth shipping though.
I am curious about if you could use the precious metal material as an anode for hydrogen production or what kinds of effects it would have on metal consumption. Just my two cent thoughts worth of curiosity.
I’m excited to see what you do next…I’m concerned that nitric won’t penetrate the deeper parts of the puck. Melt it down to shot?Alloy with copper to let the nitric in? It seemed brittle maybe it could just be crushed. Good luck, long time fan
Hello sreetips 👋 looking forward for these stock pot videos 👍 Question. In the last stannous test, the blue (shell) liquid didn’t show any precious metals. Did you count out the gold too? I’m thinking the nitric acid bath alone would not dissolve any gold from the strange fragile metal. Thanks
so maybe a dumb question... I live far from stores so getting distilled water is a pretty long trip for me. Will RO well water work? Since it does not contain Chlorine? Thanks
@@sreetips Awesome, thanks for the reply. I had another question on your reverse electroplating video. Could one use salt water instead of sulfuric acid for the electrolyte?
the real exciting part, I find, is that mr sreetips is going to "explore" a strange and unknown mix of metals... this will certainly test his knowledge and experience.... like he said, this might turn out to be interesting... bring it on :)
Hi sreetips! I'm wondering why you are getting so much smoke during the incineration, even when your material is already molten. Could it be that your mud contains some water insoluble chloride (i.e. Copper(I) chloride or Silver chloride) that reacts with the Gold to form Gold chloride and this is turning into Gold containing smoke here?
@@sreetips maybe a local art college can use it for casting or sculpture. I would if I wasn't on the other side of the planet. I am using E waste for metal for my new casting hobby.
I see many people commenting on the copper waste. It will cost more for the chemicals to separate than what it is worth in copper value. (In the US/Ca/Eu)
Sreetips: I throw away the copper because it's not worth my time or effort.
BigstackD: *angry Australian noises*

@@sreetips This is the first comment I've seen mentioning this. I've worked with borax flux a bit and it makes glass (like what you had there) when melted. So I think Maboo above is right, and what you made is silver infused borax flux/glass. Cheers!
I was only thinking recently this must be due soon! Cant wait to see this Sreetips will watch when I have the time. New knowledge and skills will make this even better I am assuming. Cant wait
Looks like you've got some interesting folks watchin your videos Sreetips . I always read some of the comments and look forward to see what you discover in that "puck" .
Fantastisk interessant å følge denne kanalen😊
Never a dull moment in Streetips lab. Fun stuff...
I've always wanted to see a stock pot find!
Hi
Thanks for the videos you share on UA-cam
I dissolved five kilograms of computer boards, including RAM and CPU, first with nitric acid, and after filtering and washing the boards, they were dissolved in acidic acid, then neutralized with urea, and finally with smb powder. The color of the solution changed to brown. Yes, but after 12 hours, no sediment was obtained. Thank you for your help
You’ve probably got so little gold that it’s not enough to detect.
love these videos, the stock pots are my favorite! Keep up the great work sreetips we appreciate you!
Sreetips is baffled
God help the rest of us!!
🤣
The stock pot haunts me in my dreams!
Very interesting on how the brittle has no precious metals except silver. Can't wait to see how this experiment shows what happened and why it separated from the other metals. My brain has been tickled haha
Sreetips: Copper is by far one of the most toxic metals when it is in solution and were it copper chloride I would agree with you that putting it through cementation in your iron tank would be very effective. However, Copper Nitrate does not react as well with iron and produces a mix of both Iron nitrate and copper nitrate in solution afterwards. Have you considered the Copper Cycle? Copper Nitrate is mixed with a small amount of Sodium Hydroxide (Lye), allowed to convert into copper Hydroxide and sodium nitrate. If you then heat the solution ( I put it outside in sunlight on my back porch) it converts the copper hydroxide to copper Oxide which is easily filtered and can be bagged and sold or contained, labelled and disposed of safely. The clear solution leftover makes a very good fertilizer and is copper free. Give it a try!
Good way to start my day, hangover cure.
Yey! another Stock Pot!
Let us see how much you can recover this time.
and for the copper-stuff:
How about sending some of it over to BigStackD? He can make some nice stuff (maybe even "Nordic Gold") from it and melt it into an ingot.
Unfortunately it would cost more to ship than it’s worth
Your high temperature oven is an exceptional tool.
If you have a cupel, you could have added 10 grams of lead to the melted metals that got you side tracked, and it would have oxidized off the crap metals, and the result would have been a Precious Metal button, that you could then add your silver to if you wanted to inquart and the refine as you normally would.
The benefit of cupelling is that 99.99% of the trash metals are oxidized off into the cupelling cup and all you have left is pure precious metals.
Since you have the perfect tool for the fire assay process, seems a shame not to use it for just this situation.
I don’t know how
@@sreetips Jason @ mbmmllc has lots of videos about doing the cupellation process.
I know you're a busy man, however, one more tool in your tool bag wouldn't hurt.
You're channel is the most instructive in so many ways, so Thank You for your incredible work and instruction.

sorry forgot to put the UA-cam link in for you.
Cuppelation is not beneficial here. There is very little base metals. Only metals copper and above. It was an incineration step, it wasnt meant to be melted into a bead. The acids are what sreetips knows and does very well. Thoudands of hours of research, trial and error. I suspect sreetips will eventually forgo incineration entirely in his stockpot videos as his process develops.
@@NOFX0890 "fire assay" is the primary step in commercial precious metal processing.
If being contrary just to be contrary was you goal, congrats.
Learning additional processes, is never a bad thing.... so exactly what was your point?
Even though I have the Refining Precious Metal Wastes book by C. M. Hoke I retain more visually. 👍🏽
I think most people do 👍
There was a first edition online....unread, it hadnt even had the spine cracked. A missed opportunity for me to get it in hardcover.
You would likely benefit from the information on alloys available through the use of a hand held or bench model XRF analyser set up for precious metals. It must be great to a print out of the alloy of a lump of random waste alloy, it would also give you a map to the recovery route for each precious component of your metal wastes.
$23k to buy. $1500 per week, $4500 per month to rent. Plus a visit from local authorities to verify proper use (because it shoots radiation). I’m nearly flat broke and deeply in debt - too rich for me. I’m just a poor-man’s hobby refiner.
Can't wait to see how much you get been wanting to see how to get paladium and other metal two thumbs
I saw the thumbnail and thought “ooo mama whatever that brown stuff is I bet it’s gon taste goooood” then I realised what channel this is 😂
i also just cement out the copper and then filter it off then to the waste..refiners use copper only foor cementing silver out :-)
copper bars are gettin expensive, sir ;)
you know that your local scrap yard will buy that copper right? seems sort of wasteful to throw it away when you could get something for it even if it is just beer money...or is that what you meant when you said you were going to toss it out?
Even if you can't get much or anything for it from the scrap yard, it's still a waste to just toss it. The impact of mining and refining is pretty significant; most metals are basically 100% recyclable, compared to plastic, which basically doesn't get recycled at all. And that bucket of copper still has a lot more value than chasing like a few grams of silver during refining.
If copper is valuable enough that people steal it from construction sites, it's valuable enough to recycle.
The recycler won’t touch it
Give that cemented copper to BigStackD casting. He doesn't care what he's putting into his crucible.
Big stack is awesome -
OMG! It's happening. Stay calm!
Wow Awesome , Nice Job 👍🏽as always
Those silver crystals look like Christmas tinsel
Oh this is great, sometimes I feel like you do all the work for me lmao
"Rinse with hydrochloric acid" and other tips your dentist won't tell you, watch to learn more!
At 9:05, could you re-use the filtered liquid to rinse the sludge down into the filter? That way you could reduce the amount of HCl to pay for.
Well that was an exciting start! Good problem solving, though. Curious about the silver glass thing. Love to know what made that.
Who knows what compounds lurk in the stock pots of men.
Balrogs....
Too bad you aren't local. I would like to try my hand at refining some of the metals out of that copper through electroplating. Its not worth shipping though.
Hi Sreetips. Could you make a video on how to remove plated silver with reverse electroplating without the use of dangerous acids? Thank you
Good grief man, how much stuff do you process a month? Always appreciate the waste treatment info too. Can't wait til part 2. Thanks again.
I am curious about if you could use the precious metal material as an anode for hydrogen production or what kinds of effects it would have on metal consumption. Just my two cent thoughts worth of curiosity.
I don’t know
Coppers worth heaps please refine some i wanna see hahahaha
Waited long for this series
I’m excited to see what you do next…I’m concerned that nitric won’t penetrate the deeper parts of the puck. Melt it down to shot?Alloy with copper to let the nitric in? It seemed brittle maybe it could just be crushed. Good luck, long time fan
Part 2 uploading
Hello sreetips 👋 looking forward for these stock pot videos 👍
Question. In the last stannous test, the blue (shell) liquid didn’t show any precious metals.
Did you count out the gold too? I’m thinking the nitric acid bath alone would not dissolve any gold from the strange fragile metal.
Thanks
Correct
so maybe a dumb question... I live far from stores so getting distilled water is a pretty long trip for me. Will RO well water work? Since it does not contain Chlorine? Thanks
I don’t know. Well water can have minerals that may affect it.
@@sreetips thank you. I enjoy that you respond to questions. I will play is safe and the next time I'm make it to town I will grab a few gallons
I know you say its not worth the time or effort, but I'd still love to see a video and what would go into recovering the copper.
Could you make a video on how to take care of the waste solution after the iron has pulled all the copper out?
I have one called “waste treatment”
@@sreetips Awesome, thanks for the reply. I had another question on your reverse electroplating video. Could one use salt water instead of sulfuric acid for the electrolyte?
I don’t think so but I’ve never tried it.
the real exciting part, I find, is that mr sreetips is going to "explore" a strange and unknown mix of metals... this will certainly test his knowledge and experience.... like he said, this might turn out to be interesting... bring it on :)
Hi sreetips!
I'm wondering why you are getting so much smoke during the incineration, even when your material is already molten. Could it be that your mud contains some water insoluble chloride (i.e. Copper(I) chloride or Silver chloride) that reacts with the Gold to form Gold chloride and this is turning into Gold containing smoke here?
Could be
I am sure one of the local community groups would love to have your waste copper, it may provide some much needed funding.
The waste recyclers won’t touch it. Too much contaminating with other metals
@@sreetips maybe a local art college can use it for casting or sculpture. I would if I wasn't on the other side of the planet. I am using E waste for metal for my new casting hobby.
I see many people commenting on the copper waste. It will cost more for the chemicals to separate than what it is worth in copper value. (In the US/Ca/Eu)
Correct. To a refiner, copper is waste
@@sreetips can’t wait for part next! Thank you for all you do!
I always take my wastes and put them in a 5l beaker and let it settle pull off the excess filter incinerate then process
Love the stockpot!
